TUBULAR VALVE.

Application filed December This invention relates to a tubular valve for internal combustion motors, the general object of the invention being to provide a single tubular valve, rotated from the crank shaft, for controlling both the inlet and ex haust passages of the cylinders of the motor.

This invention also consists in certain other features of construction and in'the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. y

In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of a motor supplied with the invention.

Figure 2 is a longitudinal sectional view through Figure 1. I

Figure 3 is a top plan view.

Figure 4 is a section on line 4-4 of Figure 2.

Figure 5 is a section on line 5-5 of Figure 2. v

Figure 6 is a section on line 6-6 .of Figure 3.

Figure 7 is a view of the sleeve valve.

As shown in these views, a cylindrical valve casing 1 extends horizontally across the top of the motor, which is shown at A and has its interior in communication with each cylinder of the engine by the'pair of ports 2, one port being the inlet port and the other the outlet or exhaust port. A housing 3 is arranged on the top of the motor and encloses the cylindrical valve casing 1. The inlet manifold B and the exhaust passages formed thereby are in vertical. alignment with the ports 2. A tubular Inemher 5 is arranged within the cylindrical valve casing 1 and is spaced therefrom and the ends of said member may be suitably connected with the housing. This member has vertically arranged passage forming parts 6 therein which are in alignment with the ports 2 and the passage forming parts 4. A. tubular valve 7 is arranged in the space between the member 5 and cylinder 1 and- 4, 1925. Serial m. 75,896.

has ports 8 therein for controlling the inlet and exhaust passages of the/device as the valve is rotated from the crank shaft through means of the chain 9 and the sprocket 10, the latter being connected with one end of the valve and arranged in a chamber 11 formed in one end of the housmg. Thusit will be seen that as the tubular sleeve valve is rotated by the crank shaft, its ports will come into register with the ports 2 of the cylinders of the motor and thus open said ports to the exhaust and inlet manifolds through means of the passages in parts 4 and 6, so that the explosive charges can enter the cylinders of the motor and the exhaust gases can escape therefrom.

Water is supplied to the housing 3 and to the interior of member 5 through the connections 12, one end of member 5 being connected with the water jacket through a substantially U-shaped connection 13. This arrangement affords cooling means for the valve parts. The parts can be lubricated in any desired manner and if necessary, rings *may be placed on the sleeve valve etween the ports to make a leak-proof joint.

This arrangement will provide a quiet motor as there are no tappets and other parts to make a hammering noise: there are no valves to grind and carbon collecting on the valve will add to its efficiency by making a tighter joint between the parts; there is but one moving part so that wear is reduced to a minimum and the parts can easily be adjusted if they should get out of adjustment. I

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangementof the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is In an internal combustion motor, a housing arranged on the top of said motor, a cylinder disposed in the housing and having ports communicating with the cylinders of the motor and with the manifolds thereof,

a stationary tubular member arranged within the cylinder and spaced therefrom and having transverse passages extending therethrough in alignment with the ports of the cylinder, a rotatably mounted sleeve valve arranged in the space between said station- ,ary tubular member and cylinder respecstationary tubular member, and said means lncludlng a connection between the Water acket of the motor and one end of said tubular member and a U-shaped connection between the Water jacket and the opposite end ofsaid tubular member.

In testimony whereof I aflix my signature.

PAUL J. SAILER.
